Abstract

One of the biggest challenges in using the Internet to replace more traditional communications is Security. In the past, companies have maintained their own modem bank dial-up access to company resources so that critical data wasn't being transmitted over the public network. Secure Shell is a protocol that provides authentication, encryption and data integrity to secure network communications. Secure Shell offers a good solution for the problem of securing data sent over a public network. For example, using Secure Shell and the Internet for securely transferring documents and work products electronically, rather than using a traditional overnight courier can provide a substantial cost savings. We propose a mobile SSH protocol which employs an application-layer handover mechanism. We have implemented the proposed SSH protocol like Open SSH and Putty. With the proposed protocol, the mobile users can switch from one wireless network to another without terminating their SSH sessions.

Abstract

Ad-hoc networks are a new paradigm in wireless communication due to its high significance in various sensitive and emergency operations. An Ad-hoc Network is a multi hop wireless network. Typically network nodes are interconnected through wireless interfaces and unlike traditional networks lack specialized nodes i.e. routers, that handle packet forwarding. Ensuring secure route doesn't guarantee a secure path for data communication in this wireless network. Any node within the secure route might be compromised at any time and become malicious to launch attack. So security for data packet should be introduced to defend against these attacks. This part of the research proposed model to implement IP Security or IPSec to for secure data transmission after route establishment in ad-hoc network paradigm.

Abstract

The aim of this paper is to present the classification problem in data mining using decision trees. Simply stated, data mining refers to extracting or “mining” knowledge from large amounts of data. Data mining known by different names as knowledge mining, knowledge extraction, data/pattern analysis, data archaeology, data dredging, knowledge discovery in databases (KDD). Data Mining, or Knowledge Discovery in Databases (KDD) as it is also known, is the nontrivial extraction of implicit, previously unknown, and potentially useful information from data. Classification is an important problem in data mining. Given a database D= {t1,t2,.…, tn}and a set of classes C= {Cl,..…, Cm}, the Classification Problem is to define a mapping f: D → C where each it is assigned to one class. It means that given a database of records, each with a class label, a classifier generates a concise and meaningful description for each class that can be used to classify subsequent records. Actually classifier divides the database into equivalence classes that is each class contains same type of records.
